CEILING-WASHING MACHINE.

Application filed October 6, 1920. Serial No. 414,975.

- 7 '0 all whom it may cmzcern Be it known that I, NnsJ. SonnnLUNn, acitizen of the United States, residing at Medford, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvementsin Ceiling-VVashin Machines; and I do hereby declarethe to lowing to be a full, clear, and exact description of theinvention, suchas will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to new and useful improvements in ceiling washingmachines and has for. its primary object the provision of a device ofthe above stated character which may be conveniently supported andoperated by a person standing on the floor without the liability ofspilling or splashing the cleaning fluid on the surrounding walls orfloor, and alsoprovide a device which 'will efliciently clean a ceilingin a comparatively short time, and thereby provide a large saving inlabor. I

Another object of this invention is the provision of a fluid containercarrying scrubbing and fluid applying mediums which may be easilyactuated by a' person standing on the floor to apply the fluid to' theceiling with a thorough scrubbing action.

A further object of this invention is the provision of a supportingelement having the fluid container so connected, thereto, that thelatter will be permitted .to assume a perpendicular position and whichwill allow the same to be manually lowered or moved away from theceiling 1n said position without lowering the supporting element.

A still further object of this invention is the provision of a ceilingwashing machine of the above stated character which will besimple,durable and efficient, and whichmay be manufactured and sold at acomparatively low cost.

\Vith these and other objects in view, as will become more apparent asthe description proceeds, the invention consists in certain novelfeatures of construction, combination, and arrangement of parts as willbe hereinafter more fully described and claimed.

For a complete understanding of my inventiomreference is to be had tothe following description and accompanying drawings, in which Fig. 1 isa side elevation partly in section illustrating a ceiling washingmachine, constructed in accordance withv my invention,

o 1 1g. 2 1s a top plan V ew of the same,

Fig. 3 is an end elevation illustrating the device,

F'g. 4 is a detail sectional View illustratlng the means of'connectingthe pole or supporting element to the container.

Fig. 5 is a detail view illustrating the means of rotating the operatingrod carried by the supporting element or-pole.

Referring indetail to thedrawings, the numeral 1 indicates as anentirety 'a washmg machine consisting of a casing 2 that includes anelongated portion 3 terminating 1n a reduced and downwardly dependingportion 4 and said elongated portion 2 has its upper end fully open toexpose a rotating brush 5 and a fluid applying roller 6. The brush androller are mounted on shafts 7 and 8 that extend through the side wallsof the elongated portion 3 of the container 2 by way of slots 9. Theslots 9 open outwardly through the upper edge of the container so thatthe brush and roller can be removed when desired. The upper portionsofthe brush and roller project above the upper edge of the container 2while their lower portions are submerged within cleaning fluid locatedwithin the reduced and downwardly depending portion 4 and a portion ofthe elongated portion 2. The shafts 7 and 8 project beyond the sidewalls of the container 2 and are rotatably supported by brackets 10which are adjustably mounted so that the brush may be raised and loweredin the container. The brackets are adjusted by nuts 12' threaded on therods 13' and the latter extend through slots in ears 14' of said- Gears11 and 12 are secured to the brackets. shafts 7 and 8 and mesh withgears 13 that are journaled on stub shafts 14 and areqin' with auniversal joint 18. The rod 17 has its lower end journaled in a bracket19 which is carried by a collar 20 splined to a supporting element orpole 21. A cross arm 22 is mounted in a bearing carried by the upper endof the pole or supporting element 21 and is held against rotationtherein by means of a set screw 24. A pair of arms 25 are journaled onthe cross arm 22 and are in turn: pivotally connected to brackets 10 ofthe container 2. Coil springs 26 are mounted on the cross arm 22 andhave one of their'ends secured thereto while the other ends bear againstthe arms 25 for normally supporting said arms in a substantiallyupwardly inclined plane and which in turn supports the container 2 in aperpendicular position.

The bracket 19 has journaled thereto a bevel gear 27 which meshes with abevel gear 28 splined to the lower end of the operating rod, 17 and saidbevel gear 27 is provided with a suitable handle 29 whereby theoperating rod 17 may be rotated, which in turn rotates the roller andbrush 5 in opposite directions.

A shaft 30 is ournaled in the side walls of the container 2 and hassecured thereon roller 31 that projects beyond the upper edge of thecontainer for engagement with the ceiling and cooperates with the roller6 in preventing the upper edge of the container from contacting with theceiling during the use of the device, but will permitthe brush 5 to havecontact with the ceiling.

\ A suitable scraper 32 is secured to the container 2 adjacent theroller 31 and is constructed from rubber or any other material suitablefor the purpose and provides means whereby the device can be used as ascraper for removing particles that may adhere to the ceiling.

A collar 33 is secured to the pole adjacent its lower end and has formedthereon a hook 34- adapted to engage a suitable belt (not shown) forattaching the supporting pole to a person, so that said person may havehis hands free to manipulate the device. A cord or flexible element 35is secured to the lower end of the reduced portion 4 and received by aneyelet 36 at the lower end of the supporting pole 21 providing aconstruction which will permit the operator to move the containerdownwardly in a perpendicular path and away from the ceiling withoutlowering the sup-porting pole 21. The pole 21 includes a plurality ofdc.- tachable sections which will permit of the pole being shortenedwhen desired and also to be taken apart when storing the device.

In operation, a person standing on the floor supports the pole 21 bymeans of the hooks 34 engaging a belt worn by the person i and therollers 31 and 6 engage the ceiling,

and the roller 6 and the brush are rotated by the handle. The roller 6moves the container gradually along the ceiling and simultaneouslyapplies cleaning fluid thereto and the brush renders a thoroughscrubbing action on the ceiling so as to thoroughly cleanse the same.

The set screw 24. provides means whereby the tension of the spring 26can be varied by adjusting the cross arm 22 in the bracket 23.

While I have shown and described the preferred embodiment of myinvention, it will be understood that minor changes in construction,combination. and arrangement of parts may be made without departing fromthe spirit and scope of the invention as claimed.

Having thus described my invention what I claim is:

1. A ceiling scrubbing machine compris ing a container, :1. fluidapplying and scrubbing medium journaled in said casing, a supportingpole, arms journaled to the supporting pole and pivotally connected-t0the container, tension means for said arms for normally supporting saidarms in an upwardly inclined plane, operating means for the fluidapplying and scrubbing medium, and a flexible element connected to thecontainer for moving said container downwardly against the tensionmeans. i
